A sword knot is a decorative loop of cord or fabric that is attached to the hilt or pommel of a sword. Its primary purpose is to secure the sword to the wrist of the person carrying it, preventing the weapon from being dropped or lost in combat. This is especially important for military personnel who might be engaged in close-quarters combat or situations where they need to move quickly and securely with their sword.

Sword knots come in various designs and materials, ranging from simple leather cords to more elaborate and ornate tassels made of silk or other fine fabrics. They often serve a dual purpose of both functional and decorative elements, adding to the overall aesthetic of the sword and its bearer.

Historically, sword knots have been used by military officers and soldiers around the world. They have been a part of military uniforms for centuries and can be found in different forms in various cultures. In addition to their practical use, they also serve as symbols of rank and status.

While not as commonly used in modern military contexts due to changes in combat styles and equipment, sword knots are still valued by collectors and enthusiasts of historical weaponry. They remain an important part of the tradition and history surrounding swords.
